Ampy is one of the coolest inventions that I see on the market today. Simply put, it is a charger for your smartphone or any other USB compatible device that is powered by your movement. This wearable device that you can strap to your ankle, arm, or put in your pocket will generate electricity with the movements you make. With each step you take while walking, each stride while running, or even with each pedal stroke while biking, Ampy will generate power.

If you walk 10,000 steps you will generate enough electricity to power an iPhone 5 for three hours. That is incredible. However if you ride a bike, you can generate the same energy in one hour of riding. And if you run, you can cut that time in half; you will generate three hours of battery life in half an hour. If I had this device when I ran cross country and track, I would have generated so much electricity.

Even better is the fact that you can check your statistics on the Ampy app. It will tell you the minutes of battery life generated, carbon footprint offset, calories burned, and you can share these stats with your friends. You can pre order your Ampy at http://www.getampy.com/pre-order. They are bit pricey but this device represents a new side of renewable energy.
